Ingredients

Vanilla extract boosts the fudge's flavor. It adds a warm, sweet taste that blends well. Sea salt enhances the chocolate flavor and balances the sweetness.
Optional Add-ins

Mini marshmallows create the swirl effect and add fun texture. Chopped walnuts or pecans bring crunch and depth. You can skip the nuts if you prefer a nut-free treat.

Step-by-Step Instructions
Preparation
- Prepare the baking dish: Start with an 8x8 inch square baking dish.
- Grease the parchment paper: Line it with parchment paper, leaving some overhang. Lightly spray the parchment with cooking spray.
Melting the Chocolate
- Combine ingredients in the saucepan: In a medium saucepan, add 2 cups of semi-sweet chocolate chips, 1 can of sweetened condensed milk, and 1/4 cup of unsalted butter.
- Stir and ensure smooth texture: Heat over low heat and stir constantly until the chocolate melts and the mixture is smooth.
Assembly of Fudge
- Add flavorings and mix: Remove the pan from heat. Stir in 1 teaspoon of vanilla extract and 1/4 teaspoon of sea salt. If you want, fold in 1/2 cup of chopped walnuts or pecans.
- Pour and spread mixture into the dish: Pour the chocolate mixture into the prepared dish. Spread it evenly into the corners.
- Create the marshmallow swirl: Drop spoonfuls of 1 cup of mini marshmallows over the fudge. Use a butter knife to swirl them gently into the fudge.
Tips & Tricks
Cooking Tips
- Best temperature for melting chocolate
Melt chocolate slowly over low heat. High heat can burn the chocolate. Stir often for a smooth mix.
- How to achieve the perfect swirl
Use a butter knife to gently swirl the mini marshmallows into the fudge. Don’t mix too much; you want to see the marshmallows.
Presentation Tips
- Decorative serving ideas
Cut the fudge into squares and place them on a pretty platter. Add a few extra mini marshmallows on top for flair.
- Using additional toppings
Drizzle some melted chocolate over the fudge. It makes for a fancy touch and adds flavor.
Common Mistakes to Avoid
- Overheating chocolate
If you heat chocolate too fast, it can become grainy and dry. Always keep the heat low to avoid this.
- Not letting the fudge set properly
Chill the fudge for at least 2 hours. This lets it firm up so you can cut it easily.
Pro Tips
- Use Quality Chocolate: The flavor of your fudge heavily relies on the quality of the chocolate chips. Opt for high-quality semi-sweet chocolate for the best results.
- Let It Cool Gradually: After melting the chocolate mixture, allow it to cool slightly before adding the marshmallows. This prevents them from melting too much and losing their shape.
- Experiment with Add-ins: Feel free to customize your fudge by adding ingredients like dried fruits, crushed candies, or different nuts for varied textures and flavors.
- Store Properly: To keep your fudge fresh, store it in an airtight container in the refrigerator, separating layers with parchment paper to prevent sticking.
Variations
Flavor Variations
You can make this fudge even better by adding flavors. One easy way is to use flavored extracts. For example, almond extract gives a nice twist to the taste. Just add a teaspoon when mixing in the vanilla. You can also use different nuts. Try pecans or hazelnuts for a new crunch. Each nut adds its own unique flavor to the fudge.
Dietary Modifications
If you follow a vegan diet, you can still enjoy this fudge. Substitute the unsalted butter with coconut oil and use almond milk instead of condensed milk. This keeps the fudge creamy while being plant-based. For those with gluten issues, this recipe is naturally gluten-free as it does not contain any flour. Just check your ingredients to ensure they are certified gluten-free.
Creative Swirls
Get creative with your marshmallow swirls! You can use flavored marshmallows like strawberry or mint for a fun twist. They add a pop of color and taste. Adding chocolate swirls is another great idea. Melt some chocolate and drizzle it on top before you swirl in the marshmallows. You can even add caramel for a sweet surprise. Each swirl adds a new layer of flavor to your fudge, making it truly special.
Storage Info
Optimal Storage Methods
To keep your fudge fresh, store it at room temperature. Place it in an airtight container. If your home is warm, refrigerate it. This helps maintain its soft texture. Just remember, refrigerating may make the fudge firmer.
Shelf Life
How long will it last? Properly stored, fudge lasts up to two weeks at room temperature. In the fridge, it can last up to a month. Always check for signs of spoilage. If it looks dry or has an off smell, it’s time to toss it.
Freezing Fudge
To freeze fudge, cut it into squares first. Wrap each piece in plastic wrap, then place them in a freezer bag. This keeps the fudge from getting freezer burn. For thawing, simply take it out and let it sit at room temperature. Enjoy your treat whenever you like!
